Welcome to Sushi Island. As an aspiring Mage Master, your mission is to collect and train a party of up to 6 low level mages and eventually win the Sushi Island Tournament. Thus rescuing your kingdom from your traitor of a brother.

You start with one of 29 Mage Apprentices and through battles of skill and strength, you can upgrade their experience points, gradually growing stronger and stronger mages until you are ready to enter the tournament for the top prize of the Sushi Cup.
